PSEUDO-SOUND GENERATOR AND PSEUDO-SOUND GENERATION METHOD

摘要

A high sound component output signal (AOSH) and a low sound component output signal (AOSL) are generatedas pseudo-sound engine sound data, on the basis of vehicle traveling information acquired by an acquisition unit. The low sound component of pseudo engine sound directed outside of the vehicle is then generated in accordance with the low sound component output signal (AOSL) by means of a vibration actuator (145j) (j = 1, 2) vibrating a bumper. In addition, vibration of the bumper causes parts of the vehicle directly or indirectly joined to the bumper to vibrate, and the low sound component of the pseudo engine sound is also generated in these parts. As a result, the low sound component of the pseudo engine sound can be generated at positions close to the engine in a gasoline vehicle, and also the low sound component of the pseudo engine sound can be effectively output to outside of the vehicle without being received inside of the vehicle.
